Here I go to this youtube video https://m.youtube.com/watch?v=-ZoBxAOczX8 then I click on Share button then Select Facebook. It redirects me to facebook with a error message saying "Sorry, something went wrong. We are working on it and we'll get it fixed as soon as we can. « Back to Home"
All other web browser works fine to share youtube videos on Facebook. N.B - I'm running Opera Mini 28.0.2254 on Android 5.1 & I always use Extreme mode with adblocking ON
